Nick Sal's HubSpot Inbound Marketing and Consulting Blog

Does your marketing department have an over-grown data base of email addresses that they haven't touched in a while? You're not alone. Many customers I consult to have the same issue: thousands of names and email addresses on a list, and no idea who on that list is a serious propect worth keeping in touch with, and which names are people who aren't interested anymore. The common solution that many organizations take is simply blasting emails out to the whole list with emails/newsletters until people start unsubscribing. There's a better way and the folks at Aboutus.Org have found it.
